Thank you Gamgee. That is some great information. 

Where you using an ATA device to hook up your modem? 

My problem is that the modems don't seem to connect, even they are set to ATS0=1. That handshake doesn't seem to be working. The modem picks up the line, then they screetch a bit but no completion of the handshake. 

So I think I'm having some issues with the ATA or Asterisk, maybe both. 

Asterisk is using ulaw, alaw for its codec. but for whatever reason modems just can't complete handshake. 

If I can ever get the modems to connect during testing, then I can move to configuring a BBS to answer using them.
